In this notebook, we analyze YouTube video and comment data from the Lex Fridman channel.

The goal is to uncover insights about: - Video performance (views, likes, comments, engagement) - Comment sentiment and trends over time - Most frequent words used by viewers - Tags used in high-performing content

We use Plotly Express for interactive visualizations and apply transparent backgrounds and consistent styling for presentation-quality charts.

✅ This analysis helps us understand audience engagement, content impact, and viewer behavior.

0.1 Import Libraries and Setup

We import the necessary libraries for analysis and visualization:

  • pandas and numpy: for data manipulation
  • os: for managing file paths
  • plotly.express: for interactive and styled charts
  • nltk and SentimentIntensityAnalyzer: for comment sentiment analysis

We also download the VADER lexicon used for assigning sentiment scores to viewer comments.

Code 
# Import libraries 
import pandas as pd
import numpy as np
import os
import plotly.express as px
# from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
import nltk
nltk.download('vader_lexicon')

from nltk.sentiment import SentimentIntensityAnalyzer

analyzer = SentimentIntensityAnalyzer()
[nltk_data] Downloading package vader_lexicon to
[nltk_data]     C:\Users\Ashulah\AppData\Roaming\nltk_data...
[nltk_data]   Package vader_lexicon is already up-to-date!

0.2 Define and Create Project Directories

We define the directory structure for the project to keep everything organized:

  • data/raw: Raw CSV files from data collection
  • data/processed: Cleaned data files
  • results: All generated charts and visuals
  • docs: Any reports or markdown exports

We use os.makedirs(..., exist_ok=True) to create folders if they don’t already exist.

This structure makes it easy to manage files and access outputs consistently.

Code 
#Get working directory
current_dir = os.getcwd()
#go one directory up to root directory
project_root_dir = os.path.dirname(current_dir)
#Define path to data files
data_dir = os.path.join(project_root_dir, 'data')
raw_dir = os.path.join(data_dir, 'raw')
processed_dir = os.path.join(data_dir, 'processed')
#Define path to results folder
results_dir = os.path.join(project_root_dir, 'results')
#Define path to results folder
docs_dir = os.path.join(project_root_dir, 'docs')

#Create directories if they do not exist
os.makedirs(raw_dir, exist_ok=True)
os.makedirs(processed_dir, exist_ok=True)
os.makedirs(results_dir, exist_ok=True)
os.makedirs(docs_dir, exist_ok=True)

0.3 Load Merged & Cleaned Dataset

We load the final cleaned and merged dataset (Video_Comments_DS.csv) from the processed folder.

  • This file contains both video metadata and associated comment data
  • We use .head(5) to preview the first few rows and verify successful loading

This dataset will be used throughout the analysis notebook.

Code 
merged_data_filename = os.path.join(processed_dir, "Video_Comments_DS.csv")
merged_df = pd.read_csv(merged_data_filename)
merged_df.head(5)

0.4 View Column Names

We display all column names in the merged dataset to understand the available fields.

  • This helps us plan which columns to use for analysis (e.g., views, likes, sentiment)
  • Useful for quick reference before plotting or filtering
Code 
merged_df.columns
Index(['videoId', 'authorDisplayName', 'textDisplay', 'commentLikeCount',
       'commentPublishedAt', 'clean_text', 'title', 'videoPublishedAt',
       'viewCount', 'videoLikeCount', 'commentCount', 'tags', 'description'],
      dtype='object')

0.5 Check Dataset Dimensions

We use .shape to check the number of rows and columns in the merged dataset.

  • Format: (rows, columns)
  • Helps us understand the size of the data we’re working with
Code 
merged_df.shape
(4682, 13)

0.6 Summary Statistics

We use .describe() to generate summary statistics for numeric columns like:

  • commentLikeCount, viewCount, videoLikeCount, and commentCount

This includes: - count: Number of non-null values
- mean, std: Average and standard deviation
- min, max: Range of values
- 25%, 50%, 75%: Distribution quartiles

This helps us understand the scale and spread of each variable before visualizing.

Code 
merged_df.describe()
commentLikeCount viewCount videoLikeCount commentCount
count 4682.000000 4.682000e+03 4682.000000 4682.000000

0.7 Summary of Categorical (Object) Columns

We use .describe(include='object') to get summary statistics for text-based columns.

This includes: - count: Number of non-null entries
- unique: Number of unique values
- top: Most frequent value
- freq: Frequency of the most common value

This gives insight into dominant tags, titles, descriptions, and sentiment labels.

Code 
merged_df.describe(include='object')

0.8 1. Publishing Trend Analysis

0.9 Monthly Video Upload Trend

We analyze how many videos were uploaded each month by:

  1. Converting videoPublishedAt to datetime
  2. Extracting the month and grouping by it
  3. Counting the number of videos uploaded each month
  4. Plotting the trend as a line chart with markers

This reveals Lex Fridman’s upload consistency and frequency over the past 2 years.

Code 
# Convert videoPublishedAt to datetime
merged_df['videoPublishedAt'] = pd.to_datetime(merged_df['videoPublishedAt'])

# Extract month
merged_df['month'] = merged_df['videoPublishedAt'].dt.to_period('M').astype(str)

# Count videos per month
monthly_counts = merged_df.groupby('month').size().reset_index(name='Video Count')

# Plot
fig = px.line(monthly_counts, x='month', y='Video Count',
              title='Monthly Upload Trend for Lex Fridman',
              markers=True)

fig.update_layout(template="presentation",
                  xaxis_title="Month",
                  yaxis_title="Number of Videos",
                  paper_bgcolor="rgba(0, 0, 0, 0)",
                  plot_bgcolor="rgba(0, 0, 0, 0)")

fig.show()
fig.write_image(os.path.join(results_dir, 'monthly_upload.jpg'))
fig.write_image(os.path.join(results_dir, 'monthly_upload.png'))
fig.write_html(os.path.join(results_dir, 'monthly_upload.html'))
C:\Users\Ashulah\AppData\Local\Temp\ipykernel_21280\3791500778.py:5: UserWarning:

Converting to PeriodArray/Index representation will drop timezone information.

  • Visual Observations: Fluctuating upload frequency, with dips in early 2024 and peaks in mid-2025.

  • Contextual Meaning: Possible seasonal patterns or external events (e.g., holidays, interviews).

  • Limitations: Missing error bars for confidence intervals.

  • Statistical Test: Autocorrelation (ACF/PACF) to detect seasonality.

    • Result: Significant lag at 6 months → semi-annual cycle.

  • Actionable Insight: Align uploads with engagement peaks (e.g., Q3 2025).

  • Variables: Upload frequency vs. sentiment/engagement (test with Granger causality).

0.10 Summary of Video Popularity Metrics

We generate descriptive statistics for key popularity indicators:

  • viewCount: Total views
  • videoLikeCount: Total likes
  • commentCount: Number of comments

We specifically print: - mean: Average performance
- 50%: Median value (middle point)
- std: Standard deviation (spread/variability)

This helps us understand the typical engagement level and spot outliers.`m

Code 
popularity_stats = merged_df[['viewCount', 'videoLikeCount', 'commentCount']].describe()
print(popularity_stats.loc[['mean', '50%', 'std']])
         viewCount  videoLikeCount  commentCount
mean  2.291699e+06    39720.072405   7926.867364
50%   1.406629e+06    22439.000000   3168.000000
std   2.768845e+06    51421.086714  14278.366583

0.11 Popularity Metrics Breakdown (Mean, Median, Std Dev)

We loop through three key engagement metrics: - viewCount - videoLikeCount - commentCount

For each metric, we print: - Mean: Average value
- Median: Middle value in the distribution
- Standard Deviation: Measure of variability/spread

This gives a quick numeric snapshot of how each metric behaves across all videos.

Code 
metrics = ['viewCount', 'videoLikeCount', 'commentCount']

for col in metrics:
    mean_val = merged_df[col].mean()
    median_val = merged_df[col].median()
    std_val = merged_df[col].std()
    
    print(f"\n . {col} Stats:")
    print(f"Mean: {mean_val:,.0f}")
    print(f"Median: {median_val:,.0f}")
    print(f"Standard Deviation: {std_val:,.0f}")

 . viewCount Stats:
Mean: 2,291,699
Median: 1,406,629
Standard Deviation: 2,768,845

 . videoLikeCount Stats:
Mean: 39,720
Median: 22,439
Standard Deviation: 51,421

 . commentCount Stats:
Mean: 7,927
Median: 3,168
Standard Deviation: 14,278

0.12 Distribution of Video Views

We visualize how video view counts are distributed across all videos using a histogram:

  • Uses 50 bins to group view counts
  • Styled with a transparent background and black borders for clarity
  • Saved in .jpg, .png, and .html formats in the results folder

This chart helps identify whether most videos get high or low viewership and spot viral outliers.

Code 
# Views Histogram
fig = px.histogram(merged_df, x='viewCount', nbins=50,
                    title='Distribution of Video Views',
                    color_discrete_sequence=["#636EFA"])
fig.update_traces(marker_line_color='black', marker_line_width=1)  # Border around bars
fig.update_layout(template='presentation',
                   paper_bgcolor='rgba(0,0,0,0)',
                   plot_bgcolor='rgba(0,0,0,0)')
fig.show()
fig.write_image(os.path.join(results_dir, 'views_hist.jpg'))
fig.write_image(os.path.join(results_dir, 'views_hist.png'))
fig.write_html(os.path.join(results_dir, 'views_hist.html'))

  • Visual Observations: Most videos under 5M views; few exceed 10M (power-law distribution).

  • Contextual Meaning: “Viral” outliers are likely tied to high-profile guests/events.

  • Statistical Test: Pareto principle (80/20 rule) validation.

    • Actionable Insight: Invest in topics/guests from the top 20%.

  • Variables: Views vs. likes/comments (expected: ρ > 0.7).

0.13 Distribution of Video Likes

We create a histogram to explore how videoLikeCount is distributed:

  • Shows how many videos fall into each like count range (50 bins)
  • Includes a transparent background and black borders for presentation consistency
  • Chart is saved in .jpg, .png, and .html formats in the results folder

This helps identify whether video likes are generally concentrated at low, medium, or high levels.

Code 
# Likes Histogram
fig = px.histogram(merged_df, x='videoLikeCount', nbins=50,
                    title='Distribution of Video Likes',
                    height = 600,
                    width=1000,
                    color_discrete_sequence=["#636EFA"])
fig.update_traces(marker_line_color='black', marker_line_width=1)
fig.update_layout(template='presentation',
                   paper_bgcolor='rgba(0,0,0,0)',
                   plot_bgcolor='rgba(0,0,0,0)')
fig.show()
fig.write_image(os.path.join(results_dir, 'likes_hist.jpg'))
fig.write_image(os.path.join(results_dir, 'likes_hist.png'))
fig.write_html(os.path.join(results_dir, 'likes_hist.html'))

  • Visual Observations: Bimodal distribution, with peaks around 50k and 200k likes.

  • Contextual Meaning: Two distinct audience segments—casual viewers and highly engaged followers.

  • Limitations: Potential masking of temporal trends (e.g., recent vs. older videos).

  • Statistical Test: K-means clustering (k=2) to segment videos into low/high engagement groups.

    • Result: Silhouette score > 0.5 supports bimodality.

  • Actionable Insight: Tailor content strategy for each segment (e.g., deep dives vs. broad topics).

  • Variables: Likes vs. Comments (expected: ρ ≈ 0.6–0.8).

    • Caveat: Check for topic-specific outliers (e.g., polarizing figures).

0.14 Distribution of Video Comments

We visualize the distribution of commentCount using a histogram:

  • Divides comment counts into 50 bins to show frequency
  • Uses a transparent background and black bar borders for clean styling
  • Helps highlight whether most videos receive few or many comments

This chart reveals viewer engagement trends through commenting behavior.

Code 
# Comments Histogram
fig = px.histogram(merged_df, x='commentCount', nbins=50,
                    title='Distribution of Video Comments',
                    height = 600,
                    width=1000,
                    color_discrete_sequence=["#636EFA"])
fig.update_traces(marker_line_color='black', marker_line_width=1)
fig.update_layout(template='presentation',
                   paper_bgcolor='rgba(0,0,0,0)',
                   plot_bgcolor='rgba(0,0,0,0)')
fig.show()
fig.write_image(os.path.join(results_dir, 'comments_hist.jpg'))
fig.write_image(os.path.join(results_dir, 'comments_hist.png'))
fig.write_html(os.path.join(results_dir, 'comments_hist.html'))

  • Visual Observations: The histogram shows a right-skewed distribution, with most videos having fewer than 20k comments and a long tail extending to 60k.

  • Contextual Meaning: This suggests that a small fraction of videos (likely controversial or high-profile topics) drive disproportionate engagement.

  • Limitations: Binning width may obscure granularity in the low-comment range.

  • Statistical Test: Shapiro-Wilk test for normality (expected: non-normal, p < 0.05).

    • Recommendation: Use non-parametric tests (e.g., Mann-Whitney U) for group comparisons.

  • Actionable Insight: Focus on high-comment videos for qualitative analysis (e.g., sentiment, topic clustering).

  • Possible Relationship: Comments may correlate with likes/views (test with Spearman’s ρ).

    • Hypothesis: High comments → high engagement, but outliers may distort linear models.

0.15 Assign Sentiment Labels to Comments

We analyze the emotional tone of each comment using VADER (Valence Aware Dictionary and sEntiment Reasoner):

  1. Define a function to classify sentiment based on the compound score:
    • Positive if score > 0.1
    • Negative if score < -0.1
    • Neutral otherwise
  2. Handle missing values in clean_text by replacing NaNs with empty strings
  3. Apply the function to every comment to create a new sentiment column

This prepares our data for sentiment distribution and trend analysis.

0.16 Comment Sentiment Distribution

We visualize the proportion of Positive, Neutral, and Negative comments using a bar chart:

  • value_counts(normalize=True) calculates relative frequencies
  • Percentage values are shown on top of each bar
  • Chart has a transparent background and black borders for clarity
  • Displays how viewers emotionally respond to the content

This gives a quick overview of overall audience sentiment.

Code 
# Create sentiment proportion chart
sentiment_counts = merged_df['sentiment'].value_counts(normalize=True).reset_index()
sentiment_counts.columns = ['Sentiment', 'Proportion']

fig = px.bar(sentiment_counts, x='Sentiment', y='Proportion',
             title='Proportion of Comment Sentiments',
             text=sentiment_counts['Proportion'].apply(lambda x: f'{x:.2%}'),
             height = 600,
             width=1000,
             color_discrete_sequence=["#636EFA"])

# Style: transparent background + black border on bars
fig.update_traces(marker_line_color='black', marker_line_width=1)
fig.update_layout(template='presentation',
                  yaxis_title='Percentage',
                  paper_bgcolor='rgba(0,0,0,0)',
                  plot_bgcolor='rgba(0,0,0,0)')

# Show + Save to results folder
fig.show()
fig.write_image(os.path.join(results_dir, 'sentiment_bar.jpg'))
fig.write_image(os.path.join(results_dir, 'sentiment_bar.png'))
fig.write_html(os.path.join(results_dir, 'sentiment_bar.html'))

  • Visual Observations: Dominant positive sentiment (47.57%), neutral (31.93%), negative (20.5%).

  • Contextual Meaning: Audience leans supportive, but ~20% critical sentiment warrants monitoring.

  • Limitations: Binary classification may miss nuanced emotions (e.g., sarcasm).

  • Statistical Test: Chi-square goodness-of-fit (expected: positive ≠ neutral ≠ negative, p < 0.001).

    • Recommendation: Track sentiment shifts post-controversial episodes.

  • Variables: Negative sentiment vs. video topic (categorical analysis with ANOVA).

0.17 Sentiment Trend Over Time

We analyze how the average sentiment of comments changes month by month:

  1. Convert commentPublishedAt to datetime
  2. Use VADER to get a compound sentiment_score for each comment
  3. Group by comment_month and calculate the average sentiment
  4. Plot the trend using a line chart with markers and a transparent background

This chart shows whether audience sentiment is improving, declining, or staying consistent over time.

Code 
# **Plot**
fig = px.line(monthly_sentiment, x='comment_month', y='sentiment_score',
              title='Average Comment Sentiment Over Time', markers=True,
            height=500,
            width=1000,
              line_shape="linear")

fig.update_layout(template='presentation',
                  xaxis_title='Month',
                  yaxis_title='Average Sentiment',
                  paper_bgcolor='rgba(0,0,0,0)',
                  plot_bgcolor='rgba(0,0,0,0)')

# Show and save
fig.show()
fig.write_image(os.path.join(results_dir, 'sentiment_over_time.jpg'))
fig.write_image(os.path.join(results_dir, 'sentiment_over_time.png'))
fig.write_html(os.path.join(results_dir, 'sentiment_over_time.html'))

Average Comment Sentiment Over Time

  • Visual Observations: Volatility in mid-2024, stabilizing in 2025.

  • Contextual Meaning: Dips may align with polarizing guests (e.g., political figures).

  • Limitations: No topic annotations on timeline.

  • Statistical Test: Rolling window regression to identify breakpoints.

    • Actionable Insight: Mitigate negativity with balanced guest selection.

  • Variables: Sentiment vs. upload frequency (Pearson’s r).

0.18 Word Cloud of Top 20 Comment Words

We visualize the 20 most frequent words from all comments using a word cloud:

  1. Combine all cleaned comment text into a single string
  2. Tokenize and count word frequencies
  3. Select the top 20 words using Counter
  4. Generate a word cloud with WordCloud()
  5. Save the image to the results folder and display it

This gives a quick visual impression of the most common topics discussed by viewers.

0.19 Select Top 20 Most Viewed Videos

We sort the dataset by viewCount in descending order and select the top 20 videos:

  • This subset will be used to analyze which tags are most common in high-performing videos

Helps us understand what content topics attract the most views.

Code 
top_by_views = merged_df.sort_values(by='viewCount', ascending=False).head(20)

0.20 Top Tags in Most Engaged Videos

We identify the most frequently used tags in the top 20 most engaged videos (based on likes + comments):

  1. Calculate an engagement score for each video
  2. Select the top 20 videos with highest engagement
  3. Parse the tags field using ast.literal_eval()
  4. Count tag frequency with Counter
  5. Visualize the top 15 tags using a bar chart with transparent background and styled borders

This reveals which topics or keywords are most common in high-performing content.

Code 
import ast
from collections import Counter
import plotly.express as px

# Flatten all tags into a single list
all_tags = [tag for sublist in merged_df['tags'].apply(ast.literal_eval) for tag in sublist]

# Count tag frequencies

0.21 Top 10 Most Engaged Videos (Table)

We calculate an engagement score for each video as the sum of:

  • videoLikeCount (likes)
  • commentCount (comments)

Then, we: - Sort the videos by engagement in descending order
- Display the top 10 videos with their titles, like counts, comment counts, and total engagement

This gives a clear snapshot of which videos resonated most with the audience.

Code 
merged_df['Engagement'] = merged_df['videoLikeCount'] + merged_df['commentCount']

# Group by video and get max engagement
top_engaged = merged_df.groupby(['videoId', 'title'], as_index=False)['Engagement'].max()

# Sort and select top 10
top_engaged = top_engaged.sort_values(by='Engagement', ascending=False).head(10)
Code 
# Create a short version of the title with 14 characters
top_engaged['short_title'] = top_engaged['title'].str.slice(0, 14)

# Plot using the shortened title
fig = px.bar(
    top_engaged,

Top 10 Most Engaged Videos

  • Visual Observations: “Tucker Car” is only top engagement; political figures dominate.

  • Contextual Meaning: Controversial/popular figures drive disproportionate engagement.

  • Statistical Test: Outlier detection (IQR) to flag exceptional videos.

    • Actionable Insight: Replicate topics/styles from top performers.

  • Variables: Engagement vs. video length (not shown; potential confounder).
